The Gallipoli Campaign (April 25, 1915-January 8, 1916), was a major land and sea operation of World War I, in which British, French, Australian, and New Zealand forces unsuccessfully attempted an invasion of Turkey. The action was confined to the Dardanelles Strait and the tip of the Gallipoli (Gelibolu) Peninsula near Istanbul. The campaign was the first major military action of Australia and New Zealand as independent dominions, and is often considered to mark the birth of national consciousness in those nations. The date of the landing, 25 April, is known as "Anzac Day". It remains the most significant commemoration of military casualties and veterans in Australia and New Zealand.

Bogle got it wrong in his lyric that “some day no one will march there at all”. The march has continued as newer wars provide more marchers. Also, young people have increasingly honoured and respected Anzac Day, including participation in the marches whilst wearing the medals of relatives (for the record, I am against that), giving rise to concern by some that it has detracted from the solemnity of the occasion.
